@Julian Andres, Sorry for trouble. But I'm still getting HASH MISMATCH with apt-get update. I don't know why but I think apt is downloading wrong file or repository has filename with wrong hash. I don't know if it's ISP traffic mangling. I have downloaded file located in by-hash/sha256 and check hash online. The hash of file is different.
Here are the screen shot. ** Attachment added: "Includes screenshot and package file" https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1785778/+attachment/5275466/+files/HASH%20MISMATCh.rar -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1785778 Title: Hash Sum mismatch Ubuntu Server 18.04.1 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1785778/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
